Does duct cleaning work?

Yes, duct cleaning does work — but its effectiveness depends on the condition of your system and what you’re trying to achieve.

✅ When Duct Cleaning Works Well:

• Visible dust buildup inside ducts or vents

• Mold, mildew, or odors in the system

• Recent renovation or construction (excess dust/debris)

• Allergy or asthma concerns tied to indoor air quality

• Pest infestations (insects, rodents, etc.)

🔧 What Duct Cleaning Does:

• Removes dust, pet dander, pollen, and debris from the duct system

• May improve airflow and system efficiency (if vents were clogged)

• Reduces indoor allergens when paired with regular HVAC maintenance

• Enhances air quality for sensitive individuals

🚫 What It Doesn't Do:

• It won’t fix underlying HVAC issues (like poor filtration or humidity)

• It doesn't significantly improve efficiency unless ducts were blocked

• It won’t keep ducts clean permanently — ongoing air filter replacement is key

🛡️ Pro Tip:

Always hire a NADCA-certified company using high-powered vacuums and rotary brushes to ensure a thorough job.
